Compact floribunda rose plant named &#39; poulpal019 &#39;

ABSTRACT

A new garden rose plant of the floribunda class which has abundant, pink flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

SUMMARY OF THE INVENTION BOTANICAL CLASSIFICATION

Rosa hybrid

VARIETY DENOMINATION

‘Poulpal019’

The present invention constitutes a new and distinct variety of garden rose plant that originated from a controlled crossing between the female seed parent ‘Poulmanti’, described and illustrated in U.S. Plant Pat. No. 11,540 issued 3 Oct. 2000, and the male pollen parent, an unnamed seedling from the same inventor. The two parents were crossed during the summer of 1997, and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘Poulpal019’.

The new variety may be distinguished from its female seed parent, ‘Poulmanti’ by the following combination of characteristics:

1. While the seed parent ‘Poulmanti’ has petal count of 40 to 50, ‘Poulpal019’ has 55 to 60 petals.

2. The upper surface of the outer flower petals on ‘Poulmanti’ are Red Group 55B-55C. ‘Poulpal019’ is White Group 155B with a faint overlay of Red-Purple Group 62D.

The new variety may be distinguished from its male pollen parent by the following combination of characteristics:

1. The pollen parent has a red flower color, while flowers of ‘Poulpal019’ are medium pink.

2. The pollen parent has a flower diameter of 40 mm. Flowers of ‘Poulpal019’ are 60 to 65 mm.

The objective of the hybridization of this rose variety was to create a new and distinct variety for garden use with unique qualities, such as:

1. Uniform and abundant pink flowers;

2. Vigorous, but compact growth;

3. Disease resistance;

4. Large flower size;

5. Dark glossy foliage.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘Poulpal019’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 1997 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘Poulpal019’ was selected in the spring of 1998 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulpal019’ by traditional budding and rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July 1998. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpal019’ are true to type and are transmitted from one generation to the next.
